高乌头药材常规项检查及高乌甲素、冉乌头碱含量测定

　　摘要：目的 对高乌头药材进行常规项检查并测定高乌甲素、冉乌头碱含量，为建立高乌头药材质量标准提供参考。方法 采集不同产地高乌头药材，采用薄层色谱法进行定性鉴别，按药典水分测定法（烘干法）、灰分测定法、浸出物测定法测定水分、灰分和浸出物，采用HPLC测定高乌甲素和冉乌头碱含量。结果 薄层色谱斑点清晰，分离度好；暂定高乌头药材中水分、总灰分及酸不溶性灰分分别不得过11.0%、12.0%、7.0%，水溶性浸出物和醇溶性浸出物分别不少于18.2%、10.6%；高乌头药材中冉乌头碱和高乌甲素含量分别不少于0.125%、0.815%。结论 本研究所建立的方法准确可靠，可用于高烏头药材质量评价。

　　Abstract： Objective To study the routine examination of Aconitum sinomontanum Nakai and determine the contents of lappacontine and ranaconitine； To provide basis for establishing the quality standard of Aconitum sinomontanum Nakai. Methods Aconitum sinomontanum Nakai were collected from different areas. A method of TLC was used for qualitative discrimination. The methods in the Chinese Pharmacopoeia were adopted for the determination of moisture content， ash content and extractives. Determination of lappacontine and ranaconitine were performed by HPLC. Results The TLC showed that the spots were clear and the separation was good. Individual provisional standards： the moisture， total ash and acid-insoluble ash content of Aconitum sinomontanum Nakai were not more than 11.0%， 12.0%， and 7.0%， respectively； water soluble and alcohol soluble extractives were not less than 18.2% and 10.6%， respectively. The content of ranaconitine and lappacontine in Aconitum sinomontanum Nakai were not less than 0.125% and 0.815%， respectively. Conclusion The method established by the study is accurate and reliable， and can be used for quality evaluation of Aconitum sinomontanum Nakai.
